Product description:

Fertilizer of uniform light-grey to dark-grey granules, grain class 2-5 mm, at least 92%. Granules coated, without permanent caking characteristics. Bulk density: 0.9-1.0 kg/dm3.

POLIFOSKA® PETROPLON includes 5% of nitrogen (N) of nitrates, 10% of phosphorus (P2O5) soluble in neutral ammonium citrate and water, that is, available in the form of mono- and bi-ammonium phosphorus, including 8% soluble in water. The fertilizer includes 30% of potassium (K2O) soluble in water, in the form of potassium chloride, that is, potash salt, 3% of total magnesium (MgO) in carbonate form and 9% of sulphur trioxide (SO3) soluble in water, in sulphate form. It also includes 0.1% of total boron (B). 

Intended use and application:

It is recommended that POLIFOSKA® PETROPLON be used first under rape and under corn and beet in both cultivation on manure and without manure. It may also be used under other root crops (potato, fodder carrot), legumes, in cultivation of vegetables (including onion, leek, cabbage and root vegetables) and in fruit cultures. Under corn and grass in field cultivation and on grassland use in limited doses, up to 400 kg/ha. POLIFOSKA® PETROPLON is recommended for soil with very low and low potassium and boron content.

The highest effectiveness is obtained with POLIFOSKA® PETROPLON used prior to sowing, when mixed with soil to a depth of 10-20 cm. This fertilizer may also be used early in spring, for top dressing on winter plants, for example rape. Permanent crops may be fertilized in spring.

POLIFOSKA® PETROPLON may be mixed immediately before spreading with urea, ammonium nitrate and nitro-chalk / Salmag, and with potash salt at any time.


Ammonium nitrogen is absorbed slowly by plants, contributing to their harmonious growth and development, and it supports absorption of phosphorus and limits excess absorption of potassium. Phosphorus in the form of ammonium phosphorus is the best available form of the element, well absorbed also where there is a deficiency of water in soil. Boron is a factor in proper development of apex and cell wall structure (it increases strength), regulates processes of florescence and pollination and setting of seed and fruit, and ensures full development of ears, spadices, siliquae and pods. This chemical composition results in good plant rooting and proper development of plants from the postemergence period, increases their freeze resistance and drought resistance and contributes to full blooming and a higher yield of high biological value.

Packaging and transport:

POLIFOSKA® PETROPLON is packaged in:
  • 50 kg ± 1% polyethylene bags with overprint;
  • Flexible containers at 500 kg ± 1% or more, the so-called big-bags.

The fertilizer must be transported while protected against water, rainfall, direct sunlight and damage to the packaging.

POLIFOSKA® PETROPLON is not classified, i.e. it is not considered a hazardous material according to the UN Orange Book and international transport codes, for example RID (railway transport), ADR (road transport) and IMDG (sea transport).

With regard to transportation using the road vehicles of the recipient or of a carrier acting on the direct instructions of the recipient, it is the recipient or the carrier who is responsible for any deterioration in the quality of the fertilizer.


Polyethylene bags with overprint of a net content of 50 kg should be stored in 10 layers at the most. Flexible containers of less than 500 kg in weight may be stored in piles of up to three layers, or in piles of two layers if weight exceeds 500 kg. In the case of pallet storage, loading units of up to 0.9 m in height are stored in piles of four layers, and loading units of 0.9 m to 1.8 m in height in piles of not more than 3.6 m.

The fertilizer should be stored in clean and dry warehouse buildings and protected against atmospheric conditions (solar radiation, rainwater). 

In the course of transportation, handling and storage, the regulations in force should be observed.


In the event of irritation of skin and eyes, wash with plenty of water. Dust masks and safety goggles are recommended. If swallowed accidentally, seek medical advice. Nontoxic, odourless, non-flammable fertilizer.
